Hey dudes is this white powdery mildew? I'm in my 1st week of flower. My RH is between 45-57, My temps are 65-70 at night and 75-77 lights on. I Run a 4x4 tent one 12 inch oscilating fan on the floor, One 12 inch oscilating wall mount fan. Also have a filtered 6" intake powered by a 6 inch vortex fan. I have crazy airflow. Could this just be water spots? I have caps bennies foliar coming in tomorrow and plan on giving my plants the spray down. Thanks dudes!
